|a| = b gives
a =b or a = -b
so,
|-x| = -10
gives
-x = -10 or -x = 10
x = 10, -10
now let us verify,
when x = 10, |-10| = +10 and it is not = -10
so, x= 10 is NOT a solution.
when x = -10, |-(-10)| = |10| = 10 and it is not = -10
so, x= -10 is NOT a solution.
hence, this equation does not have a solution.
If we know that |...| can never be negative, we can directly deduce that this equation does not have any solution.
V= W × H × L
81000 = 30 × H × 45
81000 = 1350× H
81000/1350 = 1350/1350× H
H = 60 cm
Answer:
dont know what the expressions are but imma just guess its doing scientific notation, 8.73 x 10^-11
Step-by-step explanation:
40 in2.
To find the area you multiply the width by length so you would have to find what multiplied by what would equal 100. This gives you the answer of 10. To find the perimeter you add up all the sides and because a square has 4 sides you would add 10+10+10+10 which equals 40. Hope this helped!
